I went to RSPB Rye Meads yesterday and after a 3 hour wait a male kingfisher turned up followed by 2 females who proceeded to fight. They were locked beak to beak and were trying to drown each other in the water. After several minutes one female chased the other off but it returned several times before giving up and leaving. Meanwhile the male had been perched on a log watching the battle and paired off with the victorious female. The pair spent the rest of the day sorting out their nest hole in the bank.
